What is lithosphere starting depth in km?
The lithosphere typically starts at a depth of about 0 kilometers at the Earth's surface, extending down to approximately 100 kilometers (62 miles) beneath the surface. It encompasses the crust and the uppermost portion of the mantle. The exact depth can vary depending on tectonic settings, with thicker lithosphere found in continental regions compared to oceanic areas.
The Gutenberg Discontinuity is found beneath this layer of the lithosphere?
The Gutenberg Discontinuity is found beneath the Mohorovičić discontinuity (Moho) in the lithosphere. It is located at a depth of about 70 km to 400 km below the Earth's surface. This boundary separates the upper mantle from the lower mantle.
Is the lithosphere and asthenosphere boundary above or below the Moho?
The boundary between the asthenosphere and the lithosphere is normally below the Moho (which marks the boundary between the crust and the mantle). The exception to this is below mid-ocean ridges where the moho and the lithosphere / asthenosphere boundary are at the same depth.
What is the outer shell of Earth that extends to a depth of 100km?
The outer shell of Earth that extends to a depth of 100km is known as the lithosphere. It consists of the crust and the uppermost part of the mantle and is divided into tectonic plates that float on the semi-fluid asthenosphere below.
What is the relatively soft layer of rock below the lithosphere?
The softer layer below the lithosphere is the asthenosphere. The asthenosphere begins at a depth of approximately 150 km. It has convection currents that arise from the heating and subsequent rising of material from the lower asthenosphere. These convection currents drive the movement of lithospheric plates at the surface, and are the cause of tectonic activity.
How many km is the earths lithosphere from the earths surface?
The Earth's lithosphere can vary in depth from 5 km at the ocean ridges to 200 km underneath mountain ranges.
What is the athenosphere and what is it located between?
The asthenosphere is a region of Earth's upper mantle that is partially molten and flows slowly, allowing tectonic plates to move. It is located beneath the lithosphere and extends to a depth of about 200 kilometers below the surface.

How does temperature change with depth below earths surface?
temperature increases with depth
How far below the earths surface do earthquakes occur?
Earthquakes can occur at varying depths below the Earth's surface, typically ranging from near the surface to around 700 kilometers deep. The depth of an earthquake's focus can provide insight into the type of earthquake and the tectonic plate boundary where it occurred.
Is the lithosphere and asthenosphere boundary above or below the Moho?
The boundary between the asthenosphere and the lithosphere is normally below the Moho (which marks the boundary between the crust and the mantle). The exception to this is below mid-ocean ridges where the moho and the lithosphere / asthenosphere boundary are at the same depth.

The outer shell of Earth that extends to a depth of 100km is known as the lithosphere. It consists of the crust and the uppermost part of the mantle and is divided into tectonic plates that float on the semi-fluid asthenosphere below.
What rock can melt at a depth of about below earths surface?
50km
What is the pressure at 500 m below the surface?
At a depth of 500 m below the surface, the pressure would be approximately 5 atmospheres (1 atm for every 10 m of depth).
What is the lithosphere's temperature?
The temperature of the lithosphere can vary depending on factors such as depth and location. Generally, the temperature increases with depth, with the top of the lithosphere being cooler than the lower parts. At the surface, temperatures can range from around 0°C in polar regions to over 50°C in hot desert areas.
What is the relatively soft layer of rock below the lithosphere?
The softer layer below the lithosphere is the asthenosphere. The asthenosphere begins at a depth of approximately 150 km. It has convection currents that arise from the heating and subsequent rising of material from the lower asthenosphere. These convection currents drive the movement of lithospheric plates at the surface, and are the cause of tectonic activity.
